Does Teaching Science Lead to Atheism?

Does science lead to atheism? My short answer is "no" just like the answer given by John Wilkins and Matt Young. Their emphasis is on whether scientists are always atheists and whether those who are atheists became atheists because of science or whether they picked science as a profession because they were nonbelievers. Not all scientists are atheists, therefore science doesn't inevitably lead to atheism. That's their position.

Let's ask a different question. Would good science education in the public schools convert religious students to atheism? No, it is not true that exposing students to good science teaching will inevitably make them abandon their religion.

Is that all there is? No, the question can't be answered in such a simple manner. I think that a good science education will threaten most religious beliefs and in some cases will cause students to abandon those beliefs.

Let's imagine what a good science education would look like. The teachers would explain how science works. They would teach that scientific explanations require evidence and logic and that everyone should learn to be skeptical of all claims. Teachers would use examples like evolution, plate tectonics and cosmology to describe good science and how new ideas are incorporated into our understanding of the way things work. They would use astrology, homeopathy, and the deluge as examples of how some explanations do not conform to the expectations of science. The goal is to stimulate students to think and teach them how to do it in a scientific manner.

Imagine that there are religious students in the class. There seem to be three possible ways they could incorporate their knowledge about science into their religious worldview.

1. It will have no effect on their beliefs.2. It will cause them to question and possibly abandon some of their beliefs.3. It will reinforce and strengthen their beliefs.

I strongly suspect that more students will start questioning their beliefs when they are exposed to good science education but I admit I have no data to support that suspicion. Does anyone think that the net effect would be to strengthen beliefs or leave them unaffected?

Disentangling cause from effect here will be difficult. Science education fails to "take" on a lot of people, but some are natively inclined to accept it. Are they the same group that is natively inclined to disbelieve the folk religion of their parents? Perhaps. I think science education can and will change people's religious commitments in one sense, though - if science is seen by them as more reliable than What Their Pastor Said, the religion they do end up adopting, if any, will tend to filter out all the non-factual claims (as it does, for instance, with heliocentrism).

As with any system of examining our condition, whether it be scientific method or more abstract epistemological assessments, those systems are confined by rules and their ability to test the environment. Humans are limited by the ability to sense the environment and make reasonable abstractions from its behavior. So if there are "supernatural elements" that lie outside of that system, as most religions to some degree or another claim, the inability of science to assay those territories of existence renders it to being only able to comment on the effects those forces may have on our natural environment that it is able to assess. If scientific education does dispose to atheistic inclinations, it does so because it is unable to comment on elements outside of its system and inevitably leads to conclusions that do not incorporate supernatural factors, not because it can prove those elements do not exist. My observation has been that people's ultimate decisions regarding religious belief are shaped by their early childhood experiences, which influences their later ability to recognize these limitations.

I do think that there are competing early influences, such that a child will incline towards whatever influence is strongest in their lives. However, there are some innate dispositions, such as trusting personal experience over someone's words, and a tendency to follow those who can show they are right over those who merely assert it, that can over-rule these influences. I have a paper coming out in Synthese entitled "Are creationists rational?" which discusses this. A preprint is here.

Quotations

The old argument of design in nature, as given by Paley, which formerly seemed to me to be so conclusive, fails, now that the law of natural selection has been discovered. We can no longer argue that, for instance, the beautiful hinge of a bivalve shell must have been made by an intelligent being, like the hinge of a door by man. There seems to be no more design in the variability of organic beings and in the action of natural selection, than in the course which the wind blows.Charles Darwin (c1880)Although I am fully convinced of the truth of the views given in this volume, I by no means expect to convince experienced naturalists whose minds are stocked with a multitude of facts all viewed, during a long course of years, from a point of view directly opposite to mine. It is so easy to hide our ignorance under such expressions as "plan of creation," "unity of design," etc., and to think that we give an explanation when we only restate a fact. Any one whose disposition leads him to attach more weight to unexplained difficulties than to the explanation of a certain number of facts will certainly reject the theory.

Charles Darwin (1859)Science reveals where religion conceals. Where religion purports to explain, it actually resorts to tautology. To assert that "God did it" is no more than an admission of ignorance dressed deceitfully as an explanation...

Quotations

The world is not inhabited exclusively by fools, and when a subject arouses intense interest, as this one has, something other than semantics is usually at stake.
Stephen Jay Gould (1982)
I have championed contingency, and will continue to do so, because its large realm and legitimate claims have been so poorly attended by evolutionary scientists who cannot discern the beat of this different drummer while their brains and ears remain tuned to only the sounds of general theory.
Stephen Jay Gould (2002) p.1339
The essence of Darwinism lies in its claim that natural selection creates the fit. Variation is ubiquitous and random in direction. It supplies raw material only. Natural selection directs the course of evolutionary change.
Stephen Jay Gould (1977)
Rudyard Kipling asked how the leopard got its spots, the rhino its wrinkled skin. He called his answers "just-so stories." When evolutionists try to explain form and behavior, they also tell just-so stories—and the agent is natural selection. Virtuosity in invention replaces testability as the criterion for acceptance.
Stephen Jay Gould (1980)
Since 'change of gene frequencies in populations' is the 'official' definition of evolution, randomness has transgressed Darwin's border and asserted itself as an agent of evolutionary change.
Stephen Jay Gould (1983) p.335
The first commandment for all versions of NOMA might be summarized by stating: "Thou shalt not mix the magisteria by claiming that God directly ordains important events in the history of nature by special interference knowable only through revelation and not accessible to science." In common parlance, we refer to such special interference as "miracle"—operationally defined as a unique and temporary suspension of natural law to reorder the facts of nature by divine fiat.
Stephen Jay Gould (1999) p.84

Quotations

My own view is that conclusions about the evolution of human behavior should be based on research at least as rigorous as that used in studying nonhuman animals. And if you read the animal behavior journals, you'll see that this requirement sets the bar pretty high, so that many assertions about evolutionary psychology sink without a trace.

Why Evolution Is TrueI once made the remark that two things disappeared in 1990: one was communism, the other was biochemistry and that only one of them should be allowed to come back.

It is naïve to think that if a species' environment changes the species must adapt or else become extinct.... Just as a changed environment need not set in motion selection for new adaptations, new adaptations may evolve in an unchanging environment if new mutations arise that are superior to any pre-existing variations

Douglas Futuyma
One of the most frightening things in the Western world, and in this country in particular, is the number of people who believe in things that are scientifically false. If someone tells me that the earth is less than 10,000 years old, in my opinion he should see a psychiatrist.

Francis Crick
There will be no difficulty in computers being adapted to biology. There will be luddites. But they will be buried.

Sydney Brenner
An atheist before Darwin could have said, following Hume: 'I have no explanation for complex biological design. All I know is that God isn't a good explanation, so we must wait and hope that somebody comes up with a better one.' I can't help feeling that such a position, though logically sound, would have left one feeling pretty unsatisfied, and that although atheism might have been logically tenable before Darwin, Darwin made it possible to be an intellectually fulfilled atheist

Richard Dawkins
Another curious aspect of the theory of evolution is that everybody thinks he understand it. I mean philosophers, social scientists, and so on. While in fact very few people understand it, actually as it stands, even as it stood when Darwin expressed it, and even less as we now may be able to understand it in biology.

Jacques Monod
The false view of evolution as a process of global optimizing has been applied literally by engineers who, taken in by a mistaken metaphor, have attempted to find globally optimal solutions to design problems by writing programs that model evolution by natural selection.
